SPECIFICATION forming part of Letters Patent No'. 270,035, dated January 2, 1883. Application filed August 20, 1881. (No model.)

all whom it may concern Be it known that I, WILLIAM EGIN, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of lllassachusetts, haveinvented certain new and useful Improvements in Elevator-Buckets; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

The object of this invention is to improve elevator-buckets, lessen their cost, and increase their durability, .while obviating all danger of clogging and of injuring the belt.

My invention consists in an elevator-bucket characterized by the peculiar features set forth in the appended claims.

' The drawings illustrate the peculiarities of my invention, Figures 1 and-3 showing the buckets inperspective, Fig. 2 being a transverse section; Fig.4, a bottom view, and Fig. 5 a blank cut and punched ready for bending and riveting.

The various for: s of elevator-buckets hereeen made of two or more pieces or have had some of their angles more or less acute, involving unnecessary labor and expense in construction, with liability to clog in use--that is, not to readily and completely free themselves from the material elevated when the lift is completed. Most styles have a sharp angle at the junction of the bottom and the side next to the belt, which is further objectionable, since such angle wears'upon the belt during the 11ft or is worn by it to an in- 5 jurious extent.

the ends a a, to which they are secured by rivets d d. The ends of the bucket do not stand vertical and in parallel planes, but flare outwardly and upwardly, as best shown in Fig. 4, where the length of the bottom isseen to be considerably less than that of the top. The ends and the bottom therefore meet at an obtuse angle, more or less rounded, so as to readily discharge the material elevated; but the curves along these lines ofjunction are not so pronounced as elsewhere. The. edges of the partforming the bottom are turned up outside of the ends, to resist outward pressure thereon.

When the metal used is light 1 am accustomed to strengthen these buckets by passing suitably-shaped-strips of sheet metal,e,around the upper edge and securing them in position by rivetsf, which at the ends may serve also,

to unite the parts a and c to each other.

The rivet-holes for uniting the bucket to the belt are lettered g. Owing to their flaring character, my bucketsnest compactly for shipment.

I claim as of my invention- 1. An elevator-bucket havingits body formed of a single piece of suitable material bent to shape, with its bottom and corners rounded and its ends flaring and riveted where their edges overlap, substantially as set forth.

2. An elevator-bucket havingits body formed of a single piece of sheet metal bent to shape, with rounded bottom and corners and flaring ends, its overlapping ends being riveted together and theedges of said bucket being reenforced by a strengthening-strip, c, substantially as set forth.

In testimony whereof I hereto affix my signature in presence of two witnesses.
